The AIRAID POWERAID throttle body spacer for 1997–2003 Ford F-150 and 1997–2004 Expedition 5.4L uses a patented Helix Bore to spin incoming air, improving atomization and increasing off-idle torque in the mid-range rpm band. The unit is a true bolt-on upgrade with included mounting hardware and installs with standard hand tools without cutting or drilling.
